OWB Expression Operator

Issues while using Expression Operator

OWB is case sensitive and it does not support decode operation. Make a mistake in your expression operator and it will take you a lot of time to figure out where you went wrong. The reason being that when we validate an OWB mapping it does not validate the expression operators. So if there is an error in the expression, OWB will identify it only during code generation. The error message will simply state “Unable to generate code”.

Solution

OWB provides validation inside the expression operator. Use this. Case statements can be used instead of decode.
